Area of compound shapes

​First, draw a line to break the compound shape into basic shapes. There is more than one way to do this! Here is one way.

​Then, find the area of each rectangle by multiplying length×width.

​Now, add the areas of the basic shapes.
18+16=34

So, the area of the compound shape is 34 square feet!

​Compound shapes made of rectangles and triangles

This compound shape is made of two rectangles and a triangle. Let's follow the steps to find its area!

​First, draw lines to break the compound shape into basic shapes. There is more than one way to do this! Here is one way.

​Then, find the area of each rectangle by multiplying length×width. Find the area of the triangle by multiplying 1 2 ×base×height. It helps to write in any missing dimensions first.

​Now, add the areas of the basic shapes.
15+54+24=93

So, the area of the compound shape is 93 square feet!
